Here are two examples of some logo openers that I like. I'd like to learn to make something similar, but I'm still fairly new to After Effects. I thought I'd ask for some tips and tutorials before getting started. I don't want to copy them, but just learn about the technique.
That's really not much to do in AE - there's a good concept and design that went in the logo, but other than that it's just straight animation (timing is everything), floor reflection (Andrew Kramer has a few tutorials on that) and a light sweep. I would say that a good storyboard, thinking in advance how you want the logo to come in, and a good audio sound design will help also.
